Point the antenna up vertically (upright). Antennas radiate and receive the best signal perpendicular to the direction they point, so a vertical antenna's omnidirectional radiation pattern is strongest across the horizon.

    Serial communication Serial interface Serial interface The XBee/XBee-PRO DigiMesh 2.4 provides a serial interface to an RF link. The XBee/XBee-PRO DigiMesh 2.4 converts serial data to RF data and sends that data to any device in an RF network. The device can communicate through its serial port with any logic and voltage compatible universal asynchronous receiver/transmitter (UART) or through a level translator to any serial device.

  • Page 35: Serial Buffers

    Serial communication Serial buffers Serial buffers The XBee/XBee-PRO DigiMesh 2.4 maintains internal buffers to collect serial and RF data that it receives. The serial receive buffer collects incoming serial characters and holds them until the device can process them. The serial transmit buffer collects the data it receives via the RF link until it transmits that data out the serial port.

  • Page 36: Serial Flow Control

    Serial communication Serial flow control Serial flow control The RTS and CTS device pins provide RTS and/or CTS flow control. CTS flow control signals the host to stop sending serial data to the device. RTS flow control lets the host signal the device so it will not send the data in the serial transmit buffer out the UART.

  • Page 53: Digimesh Networking

    Network configurations DigiMesh networking DigiMesh networking A mesh network is a topology in which each node in the network is connected to other nodes around it. Each node cooperates in transmitting information. Mesh networking provides these important benefits: Routing. With this technique, the message is propagated along a path by hopping from node to node until it reaches its final destination.

  • Page 54: Network Identifiers

    Network configurations Network identifiers Network identifiers You define DigiMesh networks with a unique network identifier. Use the ID command to set this identifier. For devices to communicate, you must configure them with the same network identifier and the same operating channel. For devices to communicate, the CH and ID commands must be equal on all devices in the network.

  • Page 55: Broadcast Addressing

    Network configurations Routing Broadcast addressing All of the routers in a network receive and repeat broadcast transmissions. Broadcast transmissions do not use ACKs, so the sending device sends the broadcast multiple times. By default, the sending device sends a broadcast transmission four times. The transmissions become automatic retries without acknowledgments.

  • Page 56: Digimesh Throughput

    Network configurations Routing DigiMesh throughput Throughput in a DigiMesh network can vary due to a number of variables, including: The number of hops. If you enable or disable encryption. Sleeping end devices. Failures and route discoveries. Our empirical testing shows the following throughput performance in a robust operating environment with low interference.
  • Page 57 Network configurations Routing Unicast one hop time unicastOneHopTime is a building block of many of the following calculations. It represents the amount of time it takes to send a unicast transmission between two adjacent nodes. The amount of time depends on the RR parameter. DigiMesh networks assume that the average number of MAC-level retries across a multi-hop wireless link will be three or less.

  • Page 59: Sleep Modes

    Sleep modes About sleep modes About sleep modes A number of low-power modes exist to enable devices to operate for extended periods of time on battery power. Use the SM command to enable these sleep modes. The sleep modes are characterized as either: Asynchronous (SM = 1, 4, 5).

  • Page 60: Asynchronous Pin Sleep Mode

    Sleep modes Asynchronous pin sleep mode When synchronized, a device in Normal mode relays sync messages that sleep-compatible nodes generate, but does not generate sync messages itself. Once a device in Normal mode synchronizes with a sleeping network, you can put it into a sleep- compatible sleep mode at any time.

  • Page 61: Synchronous Cyclic Sleep Mode

    Sleep modes Synchronous cyclic sleep mode Synchronous cyclic sleep mode Set SM to 8 to enter synchronous cyclic sleep mode. A device in synchronous cyclic sleep mode sleeps for a programmed time, wakes in unison with other nodes, exchanges data and sync messages, and then returns to sleep. While asleep, it cannot receive RF messages or receive data (including commands) from the UART port.

  • Page 62: Synchronization Messages

    Sleep modes Synchronization messages Synchronization messages A sleep coordinator regularly sends sync messages to keep the network in sync. Unsynchronized nodes also send messages requesting sync information. Sleep compatible nodes use Deployment mode when they first power up and the sync message has not been relayed.

    Sleep modes Select sleep parameters Auto-early wake-up sleep option If you have nodes that are missing sync messages and could be going out of sync with the rest of the network, enabling an early wake gives the device a better chance to hear the sync messages that are being broadcast.

When this occurs the first task is to repair, replace, and strengthen the weak link with new and/or redundant devices to fix the problem and prevent it from occurring in the future.
